New research has revealed millions of UK homes are unwittingly in breach of the government's energy efficiency regulations.
A Freedom of Information (FOI request) has shown almost three-quarters of the country's privately rented homes are let without a mandatory Energy Performance Certificate (EPC).
EPCs display a property's energy efficiency on a scale one A to G and is a compulsory component whenever a building is rented, sold or constructed. Since January it is also required to be displayed on property adverts.
However, the FOI request reveals only 26% of privately rented homes across England and Wales actually comply with these rules at present. This compares with a 95% compliance figure for domestic sales and a 75% figure for social housing rentals.
The government launched its Green Deal scheme in January of this year to help increase energy efficiency in UK homes. The initiative offers energy consumers loans on items such as new boilers or wall insulation to help boost energy efficiency.
The Green Deal, EPCs and the Energy Company Obligation (ECO) all aim at cutting down carbon emissions in the home - a figure which equates to almost 40% of the country's entire energy consumption and carbon emissions
Campaign group 10:10, sent the initial FOI request.
Its acting executive director, Dave Timms, said: "Fuel poverty rates in the rented sector are high so tenants really need to see information that will allow them to choose a warmer or cheaper to heat home.
"Consumers can't make informed choices if they don't have information."
The group was established to draw attention to carbon emissions - with a target of cutting emissions by ten per cent in a year.
